Description

Technical Field

[0001] The present invention relates to the technical field of biotechnological sample storage, and particularly to a biotechnological sample storage device based thereon. Background Art

[0002] Biotechnology refers to the technology in which people, based on modern life science, combine the scientific principles of other basic sciences, adopt advanced scientific and technological means, transform living organisms or process biological raw materials according to pre-designed plans to produce products required by humans or achieve certain purposes. Biotechnology is a technology in which people use microorganisms, animals and plants to process material raw materials to provide products for social services. The storage devices of some biological samples are relatively fragile, and their poor protection performance during transportation is likely to cause the samples to break, resulting in a reduction in the research efficiency of biotechnology. Therefore, we propose a biotechnological sample storage device based thereon. Summary of the Invention

[0003] To solve the above technical problems, the present invention provides a biotechnological sample storage device based thereon, including a storage rack, a protection plate, support legs, sliding rods, positioning rods, a rotating mechanism, struts, sliding grooves and circular ring blocks.

The adjusting rack positions the pressing disk above the circular hole to facilitate clamping and fixing the top of the test tube. A thin rod is arranged at the top of the threaded rod to facilitate pushing the pressing disk into the inside of the card slot to generate a dislocation with the circular hole to facilitate storing the test tube. The pressing disk is threadedly connected to the threaded rod. A fixing mechanism is arranged at the bottom of the positioning disk. A card slot is opened at the top of the adjusting rack;

[0008] The pressing disk and the inner wall of the adjusting rack are arranged to be slidably connected. The bottom of the turntable is fixedly connected to the top of the thin rod.

[0009] Further, the fixing mechanism includes an arc plate, a vertical hole, an elastic plate, a support frame, and a circular groove rubber block. The top of the arc plate is fixedly connected to the bottom of the positioning disk. The number of arc plates is four. Vertical holes are opened on the outer surface of the arc plate. The outer surface of the support frame contacts the inner wall of the vertical hole. An arc plate is arranged at the bottom of the positioning disk to wrap the bottom of the circular hole, so that when the test tube enters the inside of the circular hole, the support frame inside the arc plate is used for support. The outer surface of the support frame is fixedly connected to the elastic plate. The inner wall of the elastic plate is fixedly connected to the circular groove rubber block;

[0010] The elastic plate is arc-shaped. The top of the elastic plate is fixedly connected to the bottom of the positioning disk.

[0011] Further, the circular groove rubber block is arranged above the support frame. A rubber pad is bonded to the top of the support frame. Contact grooves are opened on the top of the rubber pad. The arc plate is arranged above the bottom of the inner wall of the storage rack.

[0012] Further, the positioning disk includes a circular hole, a rubber ring, and a silica gel block. A circular hole is opened inside the positioning disk.

[0016] Further, the two cross slots communicate with the upper and lower ends of the cylindrical hole. The outer surface of the cross block contacts the inner wall of the cross slot. The outer surface of the rotating rod is fixedly connected to the inner wall of the round frame.

[0017] The beneficial effects of the present invention are as follows:

[0018] The present invention is provided with a protective groove at the top of the storage rack to limit the protective plate. When it is necessary to store the test tube containing the sample, the support rod is pulled to slide on the surface of the positioning rod. When the support rod moves upward, the sliding rod is used to pull the protective plate to slide inside the protective groove, so that the positioning disk can be conveniently rotated out of the storage rack to fix the test tube. When the support rod moves to the top of the positioning rod, it contacts the top of the positioning rod by elasticity to support and limit the protective plate, so that the test tube can be conveniently stored and taken by using the positioning disk. The sliding rod slides inside the sliding groove, and the sliding rod is used for positioning to avoid misalignment and jamming during movement.

[0019] The present invention twists the turntable to drive the threaded rod to rotate. When the threaded rod rotates, it uses the threaded connection to push the extrusion disk to move up and down. When the extrusion disk moves upward on the surface of the threaded rod, the thin rod can be used to push into the inside of the card slot and be misaligned with the upper part of the round hole, so as to conveniently push the test tube into the round hole for fixation. When the extrusion disk moves downward by using the threaded rod, it will squeeze the top of the test tube to clamp the test tube and increase the stability.

[0020] The test tube of the present invention will push the support frame downward by the clamping force of the extrusion disk. The rubber pad at the top of the support frame uses the contact groove to limit the bottom of the test tube to prevent it from falling off. When the support frame moves downward, the elastic plate is used to elastically squeeze the test tube to increase the stability of the test tube during storage. When the elastic plate is squeezed and deformed, it will push the round groove rubber block to squeeze and wrap the surface of the test tube to increase the protection.

[0021] When the positioning disk of the present invention needs to be adjusted, a pull rod is used to pull the round rod upward. When the round rod moves upward, the cross block at the top of the round rod will separate from the inner wall of the cross groove inside the storage rack. By twisting the round rod, the contact between the cross block at the bottom and the inner wall of the cross groove drives the rotating rod to rotate. The positioning disk moves out of the inside of the storage rack by using the rotation of the rotating rod, which is convenient for storing test tubes. When the positioning disk moves out of the inside of the storage rack, there is enough time for storing and taking test tubes, increasing convenience. When the cross block at the top of the round rod contacts the inner wall of the cross groove, the positioning disk is limited and fixed to increase stability. BRIEF DESCRIPTION OF THE DRAWINGS

[0055] A specific application of this embodiment is as follows: When storing a test tube containing a sample, when the support rod 7 drives the sliding rod 4 to move upward, the protection plate 2 moves upward inside the protection groove 12 by means of the support rod 7. When the support rod 7 moves to the top of the positioning rod 5, the support rod 7 contacts the top of the positioning rod 5 elastically to support the protection plate 2, causing the protection plate 2 to be separated from the interior of the storage rack 1. When the round rod 62 is pulled upward by the pull rod, the cross block 61 at the top of the round rod 62 is separated from the inner wall of the cross groove 60 due to the movement of the round rod 62. The cross block 61 at the bottom of the round rod 62 is inside the cross groove 60 at the bottom of the rotating rod 63, facilitating the rotation of the rotating rod 63 by the round rod 62. When the rotating rod 63 rotates, the positioning disk 20 is pushed out of the interior of the storage rack 1 by the round frame 27 for convenient storage of the test tube. When the turntable 21 is twisted to rotate, the thin rod drives the threaded rod 25 to rotate. The pressing disk 22 moves upward inside the adjusting frame 26 and separates from the positioning disk 20 due to the rotation of the threaded rod 25. The pressing disk 22 is pushed into the interior of the card slot 23 by the thin rod and separated from the top of the round hole 40, facilitating the test tube to be pushed into the interior of the round hole 40 for limiting. The test tube is stuck inside the round hole 40 by the rubber ring 41 to increase the stability of the round hole 40 for the test tube. After the pressing disk 22 is pushed to be separated from the inner wall of the card slot 23 and the turntable 21 is twisted to rotate, the threaded rod 25 is used to push the pressing disk 22 downward to press the top of the test tube to clamp and fix the test tube. When the test tube moves downward, the bottom of the test tube will contact the inner wall of the contact groove, and the rubber pad is used to protect the bottom of the test tube. The support frame 33 moves downward in the vertical hole 31 inside the arc plate 30 due to the extrusion of the test tube. The elastic plate 32 deforms due to the extrusion of the support frame 33. When the elastic plate 32 deforms, it will push the round groove rubber block 34 to press the surface of the test tube to wrap and protect the outer surface of the test tube, increasing the protection and avoiding breakage.
